SPECIFICATION forming part of Letters Patent No. 738,843, datedSeptember 15, 1903. Application filed January 3], 1903. Serial No.141,307. (No model.)

.To @ZZ whom, it may concern:

Be it known that I, SETH H. PowERs, a citizenof theUnited States,residing at Stanberry, in the county of Gentry and State of Missouri,have invented a new and useful Combined Well-Boring and'Rock-DrillingMachine, of which the following is a specification.

My invention'relatcs to a combined boring and drilling machine, and hasfor its object to provide a simple, compact, and efficient constructionand arrangement of parts capable, by the minimum adjustment, ofperforming the functions of either a boring or a drilling machine,inclusive of those necessary for carrying and emptying an auger after ithas become lledwith borings, and also to provide efficient means forcontrolling the elevation and lowering of the auger and drilltools,either manually or mechanically.

'A further and important object of the invention is to provide animproved spudding mechanism capable of imparting the desiredreciprocatory movement to the drill-tools, and in connection therewith.to provide efficient means for varying the stroke of the tools, thisportion of the mechanism being so constructed as to allow the gradualfeeding of the drill rope or cable.

A further object of the invention is to provide simple and efficientmeans for communieating motion to the spudding and other devices, andalso to communicate rotary motion to the supports for the drillingmechanism, whereby rotary motion is communicated to the drill during thespudding operation.,

Further objects and advantages of this invention will appear in thefollowing description and the novel features thereotwill be particularlypointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a combined drillingand boring machine constructed in accordance with my invention, theparts being adjusted for drilling. Fig. 2 is a partial side view of thesame. Fig. 3 is an end view. Fig. 4 is a horizontal section on the planeindicated by the line 4 4 of Fig. 2. Fig. 5 is a detail view of aportion of the master-gear or endless rack. Fig. 6 is a detail view inperspective of one of the brake devices. Fig. 7 is a similar view of anauger-holding clamp-jaw. Fig. 8 is a detail view of the clutch employedfor connecting the members of the drive-shaft. Fig. 9 is a similar viewof the spudding drum and attachments. Fig. 10 is a similar view of thelock for the bull-wheel gear. Fig. 11 is a similar view of the lockingmeans for the manuallyoperated bullwheel-rotating devices. Figs. 9, 9b,and 9 are detail views, respectively, of the spudding drum and itsattachments separated.

Similar numerals of reference indicate corresponding parts in all thefigures of thed rawings.

The supporting-frame of the apparatus em-` bodying my inventionpreferably consists of a portable base having parallel side beams 1,terminally supported by wheeled trucks and transverse connecting-bars 2,and supported by this base is a turn-table or platform 3,

provided with carrier wheels or .rollers 4 to traverse a circular track5, consisting of an -internal liange formed on a horizontal master-gearG, which is bolted permanently to the base. The turn-table or platformis provided with a central opening 7, through which the drilling andboring operations are performed. Rising from the turn-table is a derrickor frame, which preferably includes front and rear pairs oftransversely-opposite upwardlyconvergent uprights S and 9, connected attheir upper ends by a cross-bar 10, said front and rear uprights beingpreferably connected in pairs by longitudinal horizontal braces 11, uponwhich are stepped the lower ends of standards, each of which is ofsectional construction and comprises an upper movable member 12 and alower fixed member 13. The sections of the standards are securedtogether by mating bracket-plates 14, having contiguous ears 15,connected by bolts. The standards are connected at their upper ends by across-piece 16 and at an intermediate point by a cross-rod 17, uponwhich is mounted a pulley or guide 1S. ln addition to this. main frame Ialso employ an auxiliary side frame, including uprights 19, connectedwith the main frame by means of braces 20, and at the opposite sideofthe main `frame I have also shown a secondary upright 21, suitablybraced and connected with the contiguous main upright 8. It will beunderstood, however, that the specific .arrangement of the auxiliaryframing members may be varied to suit the ICQ 1 adjustment upon theshaft member 23h.

the construction illustrated the movable oroperative parts which are tobe supported thereby, but that the described construction has beendesigned to accomplish the desired objects with the minimum expenditureof material and in order to secure a desirable compactness of structure.K

Extending transversely of the frame and mounted in suitable bearingsthereon is a main shaft 22, adapted to receive motion from adriving-shaft 23, which is 'mounted vertically upon the frame and isprovided with a bevel-gear 24 to mesh with a corresponding gear 25 onthe main shaft. This driving-shaft is of sectional construction, withits lower member 23n carrying a pinion 26, which is permanently in meshwith the peripheral teeth of the master-gear 6 for continuous operationduring the rotary movement of the turn-table or platform, the latterbeing actuated by any suitable means, as by horse-power, for whichpurpose it is provided with a sweep 27 and other means forconnectingdraft-animals thereto. In practice I also prefer to employ anidle pinion 26n for permanent engagement with the master-gear and havingits spindle suitably mounted in bearings on the turn-table or platformat a point diametrically opposite to the operatin gpinion 26. The uppermember 23b of the driving-shaft carries the above-described bevelgear24, and in order that the driving-shaft members may be vconnected forthe communication of motion from the lower member to the upper member Iprovide a clutch consisting of an axially-fixed member 28 on the shaftmember 23 and an axially-movable clutch member 29 'feathered orotherwise fitted for In adjustable clutch member 29 is fitted upon asquared portion of the shaft member 23b and is connected by a link 30with a hand-lever vice 32, with which the hand-lever may be engaged whenthe clutch members are disengaged.

Also mounted in suitable bearings upon the frame parallel with the mainshaft is a counter-shaft 33, operatively geared to the main shaft,as bya sprocket-chain 34, traversingl sprocket-wheels 35 and 36, secured,respectively, to the main and counter shafts. This counter-shaft formsone member of the spudding apparatus and carries a spudding-drum n 37,consisting of parallel disks provided with traversed by'a drill-rope, ashereinafter fully explained. Secured to one or both sides of thespudding-drum is a cam 42, forming one member of a clutch, wherebymotion is communicated from the counter-shaft 33 to the drum, the latterbeing loosely mounted upon its shaft for alternate revoluble movement inopposite directions. The other clutch member consists of a clutch-arm43, pivotally mounted upon a bracket-arm 44, which lis fixed to saidshaft, the clutch-arm being preferably provided with a terminal pin 45,carrying an antifriction-roll 46 or the equivalent thereof for contactwith the face of the clutch member 42. The bracket-arm 44 is preferablybifurcated, as shown, to receive the clutcharm, and the latter isextended beyond its fulcrum-point to form atrip-arm 47, adapted forcontact with the platform or other fixed smooth-surfaced portion of themechanism in order to disengage the shaft clutch member 43 from the drumclutch member 42 and allow the return movement of the drum after thelatter has completeda predetermined angular movement in a forwarddirection. The clutch-arm is yieldingly held in its normal position bymeans of an actuating-spring 48, coiled upon a guide-pin 49, which.extends through a guide-opening 50 in thetrip-arm,the opposite end ofsaid guide-pin being secured to a projecting shouldered portion 51 ofthe bracket-arm. The solid-line arrow in Fig. 9 indicates the directionof forward rotation of the clutch-arm-carrying devices and the dottedarrow in the same figure the return movement of the drum after therelease of the clutch member 42 by the displacement of the clutch-arm.

The main drill-rope 52 extends from a drum or bull-wheel 53 to and overa pulley 54, located near the upper end of the derrick, thence to therunning or movable pulley 4l, again upwardly to the top of the derrick,and over a second pulley 55, and is attached to the upper end of adrill-tool 56 of any suitable or preferred construction, and it will beseen that the continuous rotation of the countershaft 33 during therevolution of the turntable or platform will communicate motion from theclutch-arm 43 to the spudding-drum and carry the same around, therebydrawing upon the chain 40 and elevating the drill-tools untilthetrip-arm comes in contact with a fixed object, when the release of thedrum will allow the drill-tools to drop. By placing the pin 39 indifferent alined openings of the spudding-drum the length of stroke ofthe running pulley 4l before the release of the drum from the clutch-armmay be varied to suit the conditions under which the machine isoperated. V

In order to control the operations of the bullwheel and provide for theelevation of the drill-tools by the winding of the drill rope or cable52, I employ a gear 57, fixed to the spindle 58 of the bull-wheel, and ashifting pinion 59, mounted upon the feathered or squared portion of themain shaft and adapted to be thrown into or out of the plane of the gear57 in order to communicate motion to the bullwheel or allow the freerotation thereof, as may be preferred. When it is desired to ele- IOCIIO

vate the drill-tools by the winding of the cable 52 upon the drum orbull-wheel, the spudding device is first disconnected from the mainshaft or is thrown out of gear in any suitable manner, as by the removalof the sprocket-chain 34, and the pinion 59 is moved into engagementwith the gear 57 to communicate motion to the drum-shaft 58. When it isdesired to relower the tools, the members of the driving-shaft clutchshould be disengaged to permit the opposite rotary movement of the mainshaft, and the rapidity of descent of the tools may be controlled bymeans of a brake fitted upon the main shaft and consisting of a drum GOand opposite brake-shoes Gl. and 612, properly constructed to fitopposite sides of the drum and carried,respectively, by a pivotal arm 63and a brake-lever 64, which are hinged together at their remote ends, asshown at 65. It is obvious that by depressing the brake-lever or movingits free end toward the pivotal arm 63 the brake-shoes will be forcedinto Contact with the surface of the drum to impede to a greater or lessextent the rotary movement of the shaft. It is also desirable for themanipulation of smaller tools or for raising and lowering the toolsshort distances to employ manual means requiring no particularadjustment of the parts, and hence I employ a crank-shaft 66, suitablymounted upon the frame and having a terminal key-seat to receive acrank-arm 67, an operatinggear 68, carried by said crankshaft, and agear 69, carried by the bull-wheel shaft 58. The gears 68 and 69 may beconnected for operation to communicate motion from the crank-shaft tothe-bull-wheel shaft by means of an intermediate pinion 7 O, looselyfitted upon the main shaft 22 for movement into and out of the plane ofsaid gears. This pinion '70 may be locked at any desired adjustment tocorrespondingly hold the bullwheel by means of a latch 71, mounted toslide in a suitable guide 7 2 on the frame and having an operatinghand-lever 7 3, said latch being adapted to engage between the teeth ofthe pinion; but as a means of locking the bullwheel against rotarymotion and for facilitating the gradual feeding thereof during thedrilling or spudding operation I employ, in connection with the gear G9,a locking device, including' a bolt 74:, mounted for movement radiallywith relation to said gear and springactuated, as by a coil-spring 75,arran ged upon a guide-pin 7 (5, said bolt having one extremityarranged in operative relation with the teeth of the gear G9 and havingthe other end outwardly turned to form a step 77, upon which the foot ofthe operator may be arranged to disengage the bolt from the wheel. lInconnection with the bolt I employ a latchl 7 S, adapted to hold the boltin its inoperative position and having a terminal.shoulder 7 f) to bearupon the foot-rest 77. i

In connection with the abovedescribed mechanism I also preferably employan auX- iliary cable 80, adapted for lowering auxiliary or additionallengths of drill-tools into 'the hole for connection with those alreadyin operation and also for elevating an auger preparatory to the emptyingthereof, and hence I have illustrated a drum Si, of which the spindle82is mounted in suitable bearings on the frame and carries a shifting gear83, mounted upon a feathered or squared portion of the spindle andadapted for movement into and out of the plane of a gear Si, carried bythe main shaft. This drum or auxiliary bull-wheel shaft is fitted with abrake device having a lever 645 and constructed identically ashereinbefore described in connection with the brake upon the main shaft.Said lever is used in connection with a clip 85, whereby the auxiliarydrum' may be locked against rotation during the operation of thedrilling mechanism. rope or cable extends over the hereinbeforedescribedpulley 1S, mounted uponthe trans- The auxiliary y verse rod 17 of thederrick, and in the draw- A ings it is shown attached to a drill-rodsec-A tion 56% The extremity of the shaft S2 is also constructed to forma wrench-seat in order that the auxiliary drum may be manually operated.

It will be seen from the foregoing description that from the main shaft,whichis actuated directly bya driving-shaft, of which one member is inpermanent mesh with the fixed master-gear, I am enabled to communicatemotion simultaneously or independently to either the spudding-drum shaftor the several drum-shafts and that by means of the shifting devicesreferred to it is possible to change the connection of the main shaftwith the other members without loss of time or to wholly disconnect themain shaft from the other parts of the device in order to check themotion thereof or to release said other members for the paying out ofthe connected cables.

In addition to the parts already described, however, I have providedsimple means for adapting my machine for boring, and in this connectionI provide an auger holder or clamp 86, arranged for vertical movementupon the frame supported by the platform or turn-table, but designed toengage the auger and communicate motion thereto from the rotaryplatform. In the construction disclosed this auger holder or clamp,which is illustrated in detail in Fig. 7, consists of cooperatingcorrespondingly-constructed members S6 and '86", having longitudinalslots S7 and interlocking inner ends or jaws adapted to engage theauger-shank 88. Said slots .receive vertical guides 89, extendingupwardly from the platform to horizontal braces 90, connecting the frontand rear uprights 8 and 9 of the Yderrick, and the holder members arethereby adapted for either longitudinal or vertical movement to suit themovements of the auger, but are held from lateral movement, whereby asthe platform rotates the jaws communicate motion to the au ger andaccomplish IIOv the boring operation. The specific construction ofholderjaws illustrated in the drawings embodies a tongue 91 on eachmember for engagement with a seat or loop 92 on lthe other member, thetongue and seat or loop of each member being exposed perpendicularly toeach other, whereby when the jaws of the two members are connected theyform an angular opening in which the shank of the auger is held fromrotation.

It will be understood that any ordinary construction of auger maybe usedin connection with the apparatus, and during the boring operation thesuperstructure of the derrick, including the 'standard members l2 andthe pulleys 1S, 54:, and 5.5, may be removed.

The means for raising the auger when filled consists of a crane 93,mounted at its lower end in a suitable socket in the platform and at itsupper end in a bearing in a bracket 94, extending horizontally from themain or lower portion of the derrick-frame. In the constructionillustrated this bracket consists of angularly-disposed rods havingregistering loops at their outer ends to form the abovementioned bearingand provided at their inner ends with hooks 95, which engage eyes 96 inarms 97, projecting rearwardly from the derrick-frame. It will beunderstood that this crane may be readily dismounted or replaced,according to whether the machine is to be used for boring or drilling,and in Fig. l I have shown suspended thereon an auger 98, as seen whenwithdrawn from the hole and swung outward beyond the platform foremptying. It will be understood that the auxiliary cable SO may beemployed for this purpose, as indicated by the dotted lines in Fig. l,the auger being elevated by means of said cable and engaged with theterminal hook 99 of the crane, after which the latter is swung, asindicated in said Fig. I, to discharge the borings.

From the above description it will be seen that the machine embodying myinvention is compact and includes all of the mechanism necessary foreither boring' or drilling and that the adjustment of the members tosuit it for either purpose may be accomplished with the minimum loss oftime and exertion upon the part of the operator, whereby the machine maybe controlled by the aid of the minimum number of attendants, and,furthermore, that in practice various changes in the form, proportion,and the minor details of construction may be resorted to Withoutdeparting' from the spirit or sacrificing any of the advantages of thisinvention.
